ASoC: tegra-alt: Remove unsupported modes from I2S control

Browse Source 
The I2S interfaces only support configurations where both the bit clock
and frame sync are master or are both slave. Therefore, remove support
for modes where the bit clock is master and frame sync is slave and
vice-versa from the 'I2Sx codec master mode' mixer controls.
